The 25 A rating holds across the full 40–50 °C range and only starts to derate at 55 °C (24 A) and 70 °C (23 A) — so in a warm enclosure you still get nearly the full continuous current. The 4-pole width (101.6 mm) is a standard 4-module footprint for SENTRON MCCBs — it'll drop into the same busbar or mounting plate as other 4-pole 3VA breakers. No trip indicator, no voltage trigger — just the handle position tells you the state.","metaTitle":"SENTRON 3VA1125-5GF42-0AA0 MCCB, 25 A, 4-pole, 187 kA at 240","metaDescription":"SENTRON 3VA1125-5GF42-0AA0 molded case circuit breaker, 25 A, 4-pole, TM240 release, 187 kA at 240 V.
